Wisconsin justice has problems with voter ID

The NAACP has filed a lawsuit challenging the Republican-authored law, arguing it creates an undue burden on people to obtain state-issued IDs and paying for copies of supporting documents such as birth certificates. The Wisconsin Department of Justice is defending the law.

The justices heard oral arguments in the case on Tuesday. Justice Pat Roggensack, a member of the court's four-justice conservative majority, told DOJ attorney Clayton Kowski she's concerned someone might have to pay for copies of documents needed to get an ID. She says that equates to paying the state to vote.

Kowski said some people will face a burden but 90 percent of Wisconsin residents already have an ID.
